A road circumference manhole cover cutting machine

Abstract

The invention discloses a road circumference well lid cutting machine which comprises a base, wherein a rotating rack is fixedly connected onto an outer wall on one side of the base by virtue of bolts; a driven gear is arranged inside the rotating rack; a rotating rod is welded to a central position at the bottom of the driven gear; a rotating rod seat is arranged at one end, which is far away from the driven gear, of the rotating rod; a telescopic rod is welded on the outer wall on one side of the rotating rod seat; a disc is welded at one end, which is far away from the rotating rod seat, ofthe telescopic rod. According to the cutting machine disclosed by the invention, the distance between the disc and the rotating rod seat can be adjusted according to requirements by virtue of the telescopic rod, so that the cutting radius is adjusted. A channel is erected between two adjacent discs and is withdrawn from the groove, and the cutting machine conveniently moves in the channel. On onehand, requirements of different cutting radiuses are met, the applicability is improved, and the construction cost is reduced; on the other hand, the cutting stability is ensured, deviation of the cutting position is avoided, the destruction range is narrowed, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of cutting machines, and in particular relates to a cutting machine for road circumferential manhole covers. Background technique [0002] With the development of the modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and highly intelligent automatic cutting functions are also increasing. The development of CNC cutting machines must be Adapt to the requirements of the development of modern mechanical processing industry. [0003] However, the existing circumferential manhole cover cutting machine cannot be adjusted according to the required cutting radius when in use, and the disc needs to be replaced, which takes time and effort and increases the cost. The installation method and depth of the manhole cover are different in different regions, and the cutting de...
